As a rule, both lobes of Fanaroff-Riley (FR) type-II radio sources are terminated with hotspots, but the 3C 328 galaxy is specimen an FR II-like object hotspot in only one lobe. A conceivable reason for such asymmetry that nucleus was temporarily inactive. There no energy transfer from it to during period quiescence, and so they began fade out. However, under assumption axis connecting two make...

In this text, we present a generalisation of the idea of the Implicitly Restarted Arnoldi method to the nonsymmetric Lanczos algorithm, using the two-sided Gram-Schmidt process or using a full Lanczos tridi-agonalisation. The Implicitly Restarted Lanczos method can be combined with an implicit lter. It can also be used in case of breakdown and ooers an alternative for look-ahead.

HP and Intel have recently introduced a new style of instruction set architecture called EPIC (Explicitly Parallel Instruction Computing), and a specific architecture called the IPF (Itanium Processor Family). This paper seeks to illustrate the differences between EPIC architectures and former styles of instruction set architectures such as superscalar and VLIW. Several aspects of EPIC architec...

Implicitly restarted Arnoldi methods and eigenvalues of the discretized Navier Stokes equations. Abstract We are concerned with nding a few eigenvalues of the large sparse nonsymmetric generalized eigenvalue problem Ax = Bx that arises in stability studies of incompressible uid ow. The matrices have a block structure that is typical of mixed nite-element discretizations for such problems. We ex...
